Can't get multiple servos to work simultaneously using servo easing library
Hi, all. titles not a 100% accurate. i was able to take the threeServos code example off the library's github(https://github.com/ArminJo/ServoEasing/blob/master/examples/ThreeServos/ThreeServos.ino) and butcher it to my purposes. but now i'm not able to change the motor speed, no matter what number i use for the setSpeedForAllServos() function the motors always move at the same speed. but frankly i dont even understand how the code i have here works.

It’s getting there! Comment with more details
I have a robot that looks similar to yours and I can stop an issue with your current software. The reason your entire arm is flexing when the servo stops is of course realated the weak first link between the upper part oft the arm and the socket. But an easy way to fix it (get around it) is by utilizing easing. When the servo should go from 0 to 90 degrees, make it go really slowy from 0 to 20 maybe and then reallt fast from 70 to 90 make it go slowly again. Of course you can use cubic easing to get a velocity near zero before the servo stops. A great library that you can use us ServoEasing. https://www.arduino.cc/reference/en/libraries/servoeasing/ GitHub: https://github.com/ArminJo/ServoEasing

ESP32 or Pi pico for 6dof robot arm? What do you recommend? I plan to use steppers with encoders.
You may use FastAccelStepper too https://github.com/gin66/FastAccelStepper
- problems using TMC2208 stepper driver at higher speeds.
